Jenna G
Hi ladies I'm 8dpo and started spotting dark blood, around lunch time, had some cramps with it and  also very bad hot flushes most of today, Yesterday I started getting a sore throat and flu like symptoms, and boobs been painfull since 5dpo? Very tired in the afternoon too, My cycle is 25days so due on next Monday 6days time, don't want to take a test yet as its too early, also haven't been well over the weekend? Thanks for any advice x
